       subject: TABS

      overview: Tabs are an important ingredient of PC-Type II.  Tab
                definitions permit you to:

                (1) have completely different margins defined in
                    different parts of the same document.
                (2) define which part of your text is to be single,
                    double, or triple spaced when it is printed.
                (3) toggle the automatic wrapping of your paragraphs
                    as you insert and delete characters from a line.
                (4) select the action the Tab key will have upon the
                    text.

                Tab definitions are saved within the text files in
                which they are made if such files are saved in the
                document format, i.e., files saved with a .PCT
                extension.

                The margin and tab settings of a file are shown in the
                Tab Line, normally located just above the Command Line
                and below the screen area.  As the cursor is moved up
                or down within the file, if the Tab definition
                changes, the Tab Line on your screen will reflect the
                changes.

                To modify the Tabs within a file, select the "(T)abs"
                option in the Main Menu.  When you do, the following
                menu will be displayed.

                Before describing the options in this menu, it is
                helpful to learn how Tab and margin settings
                affect the cursor movement and their effect upon the
                Tab and Shift Tab keystrokes.

                It is also important to know the difference between
                "default profile tabs", "default file tabs", and
                "active tabs" and to understand the term "QUICKTABS".






                                 229
       margins: Assume that the margin and Tab stops are set as shown
                below.

                ┌──────────────────────────────────────────┐
                │ L    I    T         T         T        R │
                └──────────────────────────────────────────┘
                NOTE: The indent margin 'I' is not required.

                With the cursor on the 'L', (left margin), if you
                attempt to move the cursor to the left, it will move
                just to the right of the 'R' (right margin) of the
                previous line.  (If you move the cursor to the left
                and you are in the first line of a paragraph, then it
                will wrap at the 'I' (indent margin) instead.)

                Pressing the Home key will move the cursor to the 'L'
                unless you are on the first line of a paragraph in
                which case it will move to the indent margin.

                Similarly, with the cursor at the 'R', moving the
                cursor to the right will move it to the left margin of
                the next line (unless the next line is the beginning
                of a new paragraph, in which case the cursor will move
                to the indent margin).

     Tab stops: The only keystrokes affected by the Tab stops (the
                'T's) are the Tab and Shift Tab keystrokes.  If the
                "(T)ab char insert" toggle is OFF, (described below),
                then pressing the Tab key will move the cursor to the
                next 'T' to the right.  If there are no more 'T's,
                then it will move the cursor to the right margin.

                Similarly, pressing the Shift Tab key will move the
                cursor to the next 'T' to the left.  If there are no
                more T's, then it will move the cursor to the indent
                or left margin.

                If the "(T)ab char insert" toggle is ON, there will be
                no effect on the Shift Tab key, but the Tab key will
                behave differently.  Assume the cursor is on the X in
                the line below and the Tab stops are set as indicated.

                With the "(T)ab char insert" toggle ON, pressing the
                Tab key will push the X and all the characters to its
                right to the right until the X is above the next 'T'
                as shown below.  A "Tab character" (shown here as
                '^'), is visible to indicate that a it has been
                inserted into the text.

               ░ aaaaaXbbbbbbbb     -->  aaaaa    ^Xbbbbbbbb
               ░     T     T     T           T     T     T

                With the cursor on the X, pressing the Backspace key
                will remove the Tab character and the text will close
                again as it was originally.
                                 230
Tab characters: Tab characters can be useful for lining up columns of
                text.  When you print files containing Tab characters,
                they are translated into spaces so they will not be
                seen and will have no effect on your printer (unless
                you modify the printer translation table).

                Tab characters come into play when you reformat a
                paragraph with left justification.  Tab characters
                will always be placed right before a Tab stop.

                Similarly, when you read a file into PC-Type II, if it
                contains Tab characters, they will be aligned so that
                the Tab will be just before a Tab stop.

                In the example on the previous page, notice the gap
                between the last 'a' and the Tab character.  This is
                actually dead space and is referred to in PC-Type II as
                a "Tab fill area" or as "Tab fill characters".

                If you press the Del key when the cursor is on such an
                area, it will have the same effect as deleting the Tab
                character itself, i.e., the entire gap will close
                immediately.

                If you insert characters to the left of a Tab
                character, the "fill area" will shrink, keeping the
                Tab character itself in the same relative position.
                When you insert enough characters so that the "fill
                area" is gone, the next character insertion will cause
                the Tab character to "jump" to the next Tab stop.




    (Z)ap tabs: There is a "(Z)ap tabs" option in the Main Menu.  This
                option will go through the entire file, line by line,
                and convert all "Tab fill characters" and all "Tab
                characters" to spaces.

                This is not the same as deleting the Tabs.  The ZAP
                option will not result in any "visible" alteration to
                the display of your file except that the Tab
                characters will disappear.  Deleting all the Tab
                characters, however, would markedly alter the display.

                If a text area is marked with paragraph (Ctrl L) or
                blocked (Ctrl B) highlighting, the "(Z)ap tabs"
                option will ask if you only want to ZAP the Tabs in
                the highlighted area or in the entire file.  You can
                thus selectively ZAP the Tabs if you so choose.





                                 231
  profile tabs: The "default profile tabs" definition is the margin
                and tab settings stored in your .PRO file.  This
                definition can only be changed through the
                Configuration Menu option "(M)odify default tabs" or
                by editing your .PRO file.

                This tab definition is responsible for providing the
                margins and tabs for non-.PCT files or for any new
                files which are created.  Once a file is loaded, the
                profile tabs are copied and become the "file tabs".

                Modifying the default tabs will have no effect on
                files already in memory, but will have an effect on
                any non-.PCT files or new files loaded later.

     file tabs: "Default file tabs" define the tab and margin settings
                for a specific file.  They are visible on the Tab Line
                at the bottom of the screen when the cursor is on the
                top line of the file.  When editing a new file, the
                "default profile tabs" are copied and become the
                "default file tabs" for the new file.

                These tabs can be modified at any time when you are
                editing the file.  If the file is saved to disk with a
                .PCT extension, the "default file tabs" are saved with
                it.  The next time you edit the file, they will be
                precisely where you left them.

   active tabs: You can insert temporary tab and margin settings
                within the file you are editing.  As you move from one
                location in the file to another, the different tab
                settings come into play.  The tab setting which
                controls the cursor in its current location is called
                the "active" tab setting.  This can be the "default
                file tabs", or a temporary tab setting.

                The active tab setting is always displayed at the
                bottom of the window being edited.  As the cursor
                moves from the domain of one tab setting to that of
                another, you will be able to see the change.

     quicktabs: QUICKTABS is not a tab setting but a configuration
                toggle switch.  (See the discussion of "QUICKTABS" in
                the "Switches" portion of the Configuration section.)
                If you know that the only tab setting you will want to
                use is the "default file tab" setting, then by turning
                the "QUICKTABS" toggle ON, you bypass most of the
                questions normally asked when you modify a tabs
                setting.  If the toggle is ON, however, you cannot
                insert temporary tab settings within your document.

                NOTE: In the discussion which follows, it is assumed
                      that "QUICKTABS" are OFF.


                                 232
       subject: FILE TAB MODIFICATION

    discussion: When you select the "(F)ile Tab modification" option
                from the Tab Setting Options menu, the Command Line
                changes into a tab and margin definition line which
                you can edit.  It might look like:
                ┌──────────────────────────────────────────┐
                │ L    I    T         T         T        R │
                │Adjust tabs - Enter when done (Esc=exit)  │
                └──────────────────────────────────────────┘

                The tab and margin definition displayed is the
                "default file tabs" setting.  If you press the Esc
                key, you will exit with no modifications registered.

                If you modify the settings of Tabs or margins and then
                press the Enter key,  the "default file tabs" setting
                will have been modified.  (For a complete discussion
                on editing the tab setting, refer to "Default Profile
                Tabs" in the Configuration section of the manual.)

                NOTE: If "QUICKTABS" is ON, this would complete the
                      Tab modification process.

                After pressing the Enter key, you will see:
                ┌─────────────────────────────┐
                │Question:                    │

                │Press Y or N                 │
                └─────────────────────────────┘

                If you answer N, no reformatting will be performed.
                If you press Y, then every paragraph in the file will
                be reformatted (unless there are "No Reformat" Special
                Lines present).

                Next, the menu below will appear.
                ┌────────────────────────┐

                │ e(X)it                 │
                └────────────────────────┘
                (This menu will be discussed in detail below as the
                topic "Tab Toggle Options".)  This menu remains active
                until you press the X or Esc key.  You can see the
                status of the Tab toggles change within the menu as
                you select the S, T or W options.

                When you are finished with this menu, the modification
                of the "default file tabs" setting is complete and you
                will be returned to the Edit mode.
                                 233
       subject: NEW TAB LINE and RESTORE DEFAULT TABS

      new Tabs: When you select the "(N)ew Tab line" option from the
                Tab Setting Options menu, a "Tab line" as shown below
                is immediately inserted into your text on the line
                below the cursor, and you will be placed in the
                Command Line to edit the new margin and Tab settings.

                ├──────────────── Tab line ────────────────┤

                Initially, this Tab line contains the identical Tab
                settings as the active Tab setting.  If you press the
                Esc key while in the Tab edit mode, the new Tab line
                will remain.  Otherwise, continue the Tab definition
                as with the "(F)ile Tab modification" above.

  restore Tabs: When you select the "(R)estore default Tabs" option
                from the Tab Setting Options menu, a "Default Tab
                line" as shown below is immediately inserted into your
                text on the line below the cursor.

                ├──────────── Default Tab line ────────────┤

                This Tab line references the "default file tabs".
                While you cannot change the margin and Tab settings,
                you are given the opportunity to modify the default
                file tab toggles at this time.

Tab line domain: The two types of Tab lines shown above can exist in
                your text file in numerous locations.  The domain of
                influence of a given Tab line is from the line itself
                down toward the bottom of the file until another Tab
                line is reached.  The "default file tabs" influence
                begins at the very top of the file. Let's look at a
                sample file.

                 TOP of FILE
                ┌────────────────────────┐ default file tabs
                │          (1)           │                .
                │                        │                .

                │          (2)           │                .
                │                        │                .
                │├── Default Tab line ──┤│ default file tabs
                │          (3)           │                .
                │                        │                .
                │├────── Tab line ──────┤│ Tab definition B
                │          (4)           │                .
                └────────────────────────┘                .

                In the example, areas (1) and (3) are controlled by
                the "default file tabs" setting.  Area (2) is
                controlled by whatever settings were made when the
                new Tab line (A) was inserted and Area (4) is
                controlled by the new Tab line (B) settings.
                                 234
       subject: ACTIVE TAB MODIFICATION

    discussion: When you select the "(A)ctive Tab modification" option
                from the Tab Setting Options menu, modify the tabs as
                described above for "Default File Tabs Modification".

                The Tabs you are modifying with this option depend
                upon the current location of the cursor.  In the
                example on the previous page, if you were in area (2)
                of the file, you would be modifying the Tab definition
                A.  If you were in area (3), you would be modifying

       subject: MODIFY ACTIVE TAB TOGGLES

       purpose: Three toggles exist for every tab line which define:
                (1) the text spacing (single, double or triple).
                (2) the action to take when the Tab key is pressed.
                (3) the state of automatic sentence wrapping.

    discussion: If you select the "(M)odify active Tab toggles" option
                from the Tab Setting Options menu, the menu below is
                shown.  This is the same menu which appears during the
                normal process of creating or modifying Tab lines.
                Selecting this option from the menu implies that the
                "active tab line" toggles are the ones which are to be
                modified.  (This menu will never appear if the
                QUICKTABS toggle is turned ON.)

                │ (W)rap paragraph  ( ON)│

                └────────────────────────┘
                Pressing S will toggle the (S)pacing line from (SNG)
                (single spacing) to (DBL) (double spacing) to (TRP)
                (triple spacing).

                Pressing T will toggle the (T)ab char insert line from
                ( ON) to (OFF).  When this toggle is ON, a tab
                character will be inserted in the text when the Tab
                key is pressed (unless you are using a hanging indent
                and the cursor is to the left of the left margin).

                Pressing W will toggle the (W)rap paragraph line from
                (ON) to (OFF).  When this toggle is ON, text within a
                paragraph will be automatically adjusted as characters
                are inserted or deleted from a line.

                The status of these toggles for the active Tabs is
                visible in the status area at the upper left hand
                corner of your screen.

                The spacing will be shown as a '1', '2', or '3'.

                If "(W)rap paragraph" is ON, it will be shown as a
                'W'.  If it is OFF, the double line border will take
                its place.

                If "(T)ab char insert" is ON, it will be shown as a
                'T'.  If it is OFF, the double line border will take
                its place.

                In the example "╔════T2W═", the active Tab toggle
                settings are "insert Tab characters", double spacing,
                and automatic wrapping.
